First time poster, please forgive ignorance.
I encountered this problem when writing a pthreaded module for Irssi (non-pthreaded).
Irssi loads modules with dlopen() and removes them with dlclose(). A segmentation fault occurs when Irssi tries to remove a pthreaded child from the address space. A description of this problem is available here and here.
Fix: a workaround is to simply build the parent (in my case, Irssi) with pthreads.
I don't know if this is a feature, quirk, or bug, but it was suggested to me to bring it to the lists' attention.
Thanks,
Max Englander
